Correlations between ratings on fatigue and depression, muscular impairment, disease duration and CTG repeat size in patients with DM1 (n = 32)
| FIS-T | FIS-PS | FIS-PHY | FI-C | |
|---|---|---|---|---|
| BDI-II | .68 ** | .68** | .65** | .64 ** |
| BDI-S | .43* | .41* | .47** | .46** |
| BDI-C | .49** | .50** | .42* | .46** |
| MIRS | .37* | .40 * | .34 | .26 |
| Disease duration (years) | .11 | .14 | .13 | .10 |
| CTG-repeats † | .06 | .08 | .09 | −.11 |
Note: FIS = Fatigue Impact scale, BDI = Beck Depression Inventory, MIRS = Muscle Impairment Rating Scale. FIS-T = total score, FIS-C = cognitive score, FIS-PS = psychosocial score, FIS-PHY = physical score. BDI-S = BDI somatic dimension, BDI-C = BDI cognitive-affective dimension. * = p < .05, ** = p < .001, † = n = 29
